Hi,
I'm facing an issue since 2 month now , no one is able to tell me what's going on. The line goes down suddently for 2 or 3 minutes and this happens everyday at the same range (~2 or 3 hours) of time . I don't have any scheduled task to cause this. ISP in his side has also made some tshoot but found nothing and is convinced that the problem is coming from our side :
Here is some log :
